Why are many basketball players wearing socks that come up past their knees?

I think it’s just fashion.

I’d say tradition.

Their legs are cold.

Seriously, the ventilation systems in some of the larger arenas are not very good – there are wind currents that pass from one portal to another. So they cover their legs for warmth.

When winter is over, they’ll go back to their regular socks.

Falling and skidding on that smooth floor causes a burn that hurts like hell! Maybe the socks are there to prevent these burns. Or to aid in sliding into the cheerleaders when they fall…

Forgive my ignorance I rarely watch sports.

Are you sure they are just socks and not calf sleeves or compression socks?

They certainly appear to be socks, @Unbroken. I own some.

Thanks, all.
